| 摘 要： | 以一小型风力机作实捌，运用2种方法分别计算垂直轴阻力型风力机的风能利用率。一种方法是通过对风力机叶片受力分析，利用风力和功率计算公式，借助Matlab工具计算；另一种方法是利用Fluent软件分析风力机在给定风速下的气动性能，仿真叶片气动流场流态，并计算叶轮的扭转力矩和风能利用系数等参数。比较2种方法的优缺点，有助于垂直轴风力机的设计研发。

| Abstract: | Taking a small drag-type vertical axis wind turbine as example,the efficiency of the drag-type vertical axis wind turbine was calculated by two different methods.With analysis of the blade stress situation and by Matlab,the first method has presented the formula of force and power,in the latter,the Fluent software was used for numerical simulation of the aerodynamic performance for wind turbines at given wind speed.The pneumatic flow field of the blade was simulated,torsional torque and the efficiency of th... |
